Corrugated Roofing Screw Round Head Pozi ZP 5mm x 50mm Bag 10

These Forgefix Pozidriv round head corrugated roofing screws are expertly designed for the secure installation of corrugated sheeting to timber subframes. Constructed with a zinc-plated finish, these screws provide enhanced corrosion resistance, ensuring durability and longevity in various weather conditions.

Product Features

• Screw Size: The screws measure 5.0 x 50mm (Pozi), making them ideal for various applications where a robust fastening solution is needed.
• Corrosion Resistance: The zinc plating serves as a protective barrier against oxidation, thereby prolonging the lifespan of the screws. This process occurs by forming a protective layer and acting as a sacrificial anode, which is particularly useful if the coating is compromised. Zinc oxide, a fine white dust that forms during oxidation, does not contribute to the degradation of the screw's integrity. Instead, it acts as an additional barrier against further oxidation, akin to the protective properties seen in aluminium and stainless steel when exposed to the elements.
• Specialized Cap Design: Each screw comes complete with a specially designed plastic fold-over cap that has a large surface area, enhancing weather resistance. This thoughtful design aids in the prevention of water ingress and provides an extra level of protection to the screw and the materials being fastened.
• Pozidriv Drive: The Pozidriv screw design offers four additional points of contact compared to standard Phillips screws. This unique aspect minimizes the risk of "camming out," allowing users to apply greater torque without slipping. The Pozidriv screw is easily identified by an embossed line at a 45-degree angle to the slots on the screw head, differentiating it from traditional cross-head designs.

Applications

These screws are specifically formulated for use in fixing corrugated sheeting to timber subframes. Their round head with a flat under-head surface allows for a smooth application on sheet materials of any type, thereby reducing the risk of deformation during installation. The combination of the Pozidriv design, corrosion-resistant zinc plating, and effective cap means that these screws are a reliable choice for roofing projects, ensuring a secure and long-lasting fit.

Whether you are a professional tradesperson or undertaking a DIY project, the Forgefix Pozidriv round head corrugated roofing screws are an essential component for achieving a sturdy and weather-resistant roofing solution.
